The thing with the first order XO is that all drivers are exposed to a wide frequency band and the 3.5 mid-range is not able to handle a high power, rated at about 50 W. Been talking this afternoon to Rob about the various alternatives for this driver now that they can no longer be rebuild not replaced. Scan speak is promoting a driver as a replacement and Rob is now working on testing to see how they compare. May know more in 2 weeks. Have a few other alternatives that may do the job but they may require some adaptations to the opening as they have a slightly larger diameter. Stay tuned as measurements and listening tests are conducted.

Jafant,
I run my 3.5’s with a pre Accuphase c260, power amp Accuphase p360, cd Marantz UD7007, tuntable denon dp55k, tonearm SME 3009, all bought used except the cd. Cables kimber KS, and Audioquest both balanced. OBLGN also gave me his eq for FREE but the pre had some issue and was never gonna able using it as only one channel worked when the tape loop was on. I then bought another bass eq on eBay, same issue. Previously I shipped my original bass eq (count is 3...) to Mr Gillum that was unable to repair (mayby I didn’t say it was 220V?) and NEVER ship it back to me (Italy).

Now I am really without music in my house and happy to listen scan speak is providing replacement, which I hope will be for both tweeter and midrange. Will the crossover need some modifications as well?
thanks

Thank You for the update after consulting Rob at CSS. Looking forward in reading more about your findings. Keep up the excellent R&D.

Happy Listening!

You own a very nice Accuphase system. I have always wanted to demo their gear. It certainly does not appear to be an electronics/speaker mismatch per se. Thank You for citing Mr. Gillum's attempt to repair the EQ and mentioning oblgny's assistance as well.  I do not have any information on wether or not these devices are repairable? Between the collection of minds here, hope there is a viable solution at issue.

3.5ers - The 3.5 EQ should be repairable. Someone here led me to a DIY schematic - very complete and thorough. I am forwarding that to Rob at CSS in case there might be some additional value there.
Regarding the 3.5 midrange - Rob has samples of a new ScanSpeak driver coming for testing. The supplier says it should need no XO modification. Rob and I will confirm that or devise a xo update kit to make it work.
